85-896 25 mm Dia. Hard Coated OD 4.0 50nm Bandpass Filter; t=3.5 mm 1200nm
The 85-896 is a Bandpass Filter, specifically designed by Edmund Optics with a diameter of 25 mm and a thickness of 3.5 mm. This filter is part of the UVFS MAL-1965 material ID family, which is renowned for its high-quality optical properties.
The Bandpass Filter is a type of optical filter that allows only a specific range of wavelengths to pass through it, while blocking other wavelengths. In this case, the 85-896 filter is designed to pass wavelengths around 1200nm, with a cut-on wavelength of 1175nm and a cut-off wavelength of 1225nm. This makes it ideal for applications that require precise wavelength selection.
The filter features hard coating on both the front and back surfaces, providing enhanced durability and resistance to scratches and other forms of damage. The coating is of the EDM 85-884 type, ensuring high-quality performance and reliability.
The filter's shape is that of a Thin Lens, which is designed to minimize optical aberrations and distortions, further enhancing its performance in various applications. The filter is currently in stock and available for purchase through the Edmund Optics website.
